IMPROVEMENT IN SAD-IRON GRINDERS.

Specification forming part of Letters Patent No. 185,386, dated December19, 1876; application filed April 4, 1876.

To all whom it may concern Be it known that I, JAMES F. BLESS, ofNewark, in the county of Essex and State of New Jersey, have invented acertain Improved Smoothing-Iron-Grinding Machine, of which the followingis a specification Myinvention consistsin the improved means of holdingsad-irons, and of adjusting them in relation to the grindstone while themachine is in motion.

Figure 1 is a plan view. Fig. 2 is a sectional elevation from the lineof e 0. Figs. 3, 4, and 5 are detailed views of a disk or wheel to whichthe irons are attached.

In grinding sad-irons by machinery it is important to have the irons putinto the machine and taken out without stopping it, and

to have the irons move back and forward across the face of the stone, sothat it may be kept level, and to provide for the different thickness ofirons that may be found mixed together, and to provide, also, forfeeding the irons to the stone, and of changing the relative speedrequired as the stone wears away. To meet these demands is the object ofthis invention.

The power is applied to the wheel A on the shaft B, on which, also, isthe grindstone C, and a pulley, a, and over this pulley passes a belt,vD, also connecting with the pulley E on the shaft 6, working on thesliding frame S. On this shaft 8 is a small gear, 0, working into alarger gear, I), on a shaft, F, below. On this shaft F is also ascrew-gear, d, and a camwheel, f. Above the shaft F, and lying acrossit, is a shaft, H, on which is a gear, I, with a concave edge, workinginto the screw-gear d, and on the same shaft is disk K, on which theirons i are placed for grinding. This disk is constructed with theapertures 2 on the face, and apertures 3 on the edge and face, throughwhich the handle a of the iron is inserted.

This handle then slips down over the end of the swing-lever 4, and thescrew 5, passing through the lever, and the end pressing against thedisk, turned after the iron is in position, throws out the outer end ofthe lever, which, pressing against the inside of the handle, holds itfirm in position for grinding; and to remove the iron it is onlynecessary to loosen the screw, when it is readily taken out. The disk isheld on the shaft H by a cap and clutch, m. This cap, with a squarehole, 0, (see Fig. 3,) slips onto the end of the shaft H,

and is held by a screw, 7', or a nut, and the pins 6, passing throughthe disk, keep it from turning on the shaft, although it is loose on theshaft. The object of having it loose on the shaft is, that it mayslideendwise, and thus be adjustable for irons of different thickness. Thespring 7 reacts the'disk, holding it against the stone, but allows it toyield,'as aforesaid, for irons of different thickness.

Another provision for this same purpose is.

in the roll 8, pressing against the inside of the disk, actuated by thespring 9 on the opposite end of the slide 10. Without this spring-rollthe disk would bind on its shaft, the pressure The power applied at A bythe belt D turns the shaft 6, and with it the gear 0, and, by means ofthe larger gear I), communicates slower speed to the shaft F. Theturning of shaft F by the screw-gear d, working in the larger gear I,gives more moderate speed to the shaft H, on which is the disk. Thisdisk then moves at such a rate of speed that an operator can put on andtake off the irons, as before shown, while the disk continues in motion.The same turning of shaft H by means of the cam f, as above shown, giveslateral motion to the disk, and the irons on its face are moved acrossthe face of the stone, back and forward, to keep it level.

To provide for stones of any size, from a new one to one much worn away,the adjustable screw-rods A, by the connecting-rod 13', making theconnection by the bevel-gears D, turned by the wheel G, move the slidingframe S to or from the stone, carrying with it the disk and the irons. Atightener-pulley will be used in connection with the belt D, to providefor these changes.

I claim 1. In a smoothing-iron-grinding machine, the disk K, having thecircular motion by means of the gears'd and I, and the lateral motion bythe cam f and rolls 1 1, in combination with the frame S, substantiallyas and for the purposes specified.

2. The disk K, loose on the shaft H, and held by the cap and clutch m,and screw 1', and made adjustable on the shaft H, for irons of differentthickness, by the springs 7 and 9, substantially as specified, and forthe purposes set forth.

3. The disk K, having the apertures 2 and 3, and the swing-lever 4 andscrew 5, for attachin g the irons, substantially as shown.

the shafts e, F, and H, to operate the disk K,

in combination with the driving-wheel A and stone G, substantially asset forth, and for the purposes specified.
